IBAN Generator & Validator
Generate structurally valid test IBANs for 87 countries and validate any IBAN with the mod-97 checksum — entirely in your browser.
Everything runs in your browser — nothing is sent to any server.The generated IBANs are dummy data for development and testing — the checksum and structure are valid, but they are not connected to any real bank account.
About this tool
This page bundles two utilities. The generator builds IBANs that pass the mod-97 checksum with the correct length and field structure for each of the 87 IBAN registry countries — where curated presets exist you can pick a real bank code, while the account digits are always random test data (never real accounts). The validator checks any pasted IBAN: country structure, character set, length, the ISO 7064 mod-97 checksum, and decomposes the BBAN into its bank code, branch and account parts, plus the SEPA membership flag. Everything runs locally in your browser; nothing is sent to any server.
